Firstly, thanks in advance for any assistance. I used the preferred method (card with white dots) and used an umbrella to block the shadow/wash-out from the sun. The calibration routine seemed to complete successfully. The image below shows the image incorrectly oriented. The camera rotation certainly seems to be an issue at 69.32. Calibration was performed with the z-axis fully raised.
I decided to add 180 degrees (changing to 0 didn’t work ) then entered the 249.32. Looks right on, maybe except slight scale issue. At this stage, I’m assuming the camera physically needs to be reoriented in the mount or can this be adjusted via software? The 2nd image below shows the new alignment.
